91       an application wishes to perform many queries, and it eliminates
96     and it encapsulates occlusion queries in "query objects" that allow
97     applications to issue many queries before asking for the result of

224         occlusion test, and so an application should not use occlusion queries
274     Is it guaranteed that occlusion queries return in order?
328         a problem beyond simple occlusion queries, this extension creates
329         a framework useful for future queries.

419         using occlusion queries, it is best to be careful about the near

445     Do occlusion queries make other visibility algorithms obsolete?
449         Occlusion queries are helpful, but they are not a cure-all.  They
